A. Description.

High pass monthly statistics have been computed by the
CCM Processor (Buja, 1992) for
20 years of T42 Case 388 and are stored on the MSS as time average
history save tapes (SAVHSTA). The filter was constructed by
P. J. Rasch and is described in the Climate Modeling Section (1993).

1. Data is computed on the following vertical pressure levels:

1000, 950, 850, 700, 500, 300, 200, 100

2. The fields are: 'Z2', 'T', 'U', 'V', 'OMEGA', 'Q' .

3. The fields were then high-pass filtered as :

'Z2HIGH'

'THIGH'

'UHIGH'

'VHIGH'

'OMHIGH'

'QHIGH'

4. Low pass data for Z2 (Z2LOW) were obtained by taking the
difference of the high pass and original.
(5.) Covariances of the filtered data were calculated as:

'ZZLOWP'

'ZZHIGHP'

'UUHIGHP'

'VVHIGHP'

'WWHIGHP'

'TTHIGHP'

'QQHIGHP'

'UTHIGHP'

'VTHIGHP'

'WTHIGHP'

'UZHIGHP'

'VZHIGHP'

'WZHIGHP'

'UQHIGHP'

'VQHIGHP'

'WQHIGHP'

'UVHIGHP'

'UWHIGHP'

'VWHIGHP'

B. Generation of Monthly Mean Statistics.

The following is a listing of the CCM Processor (Buja, 1992) Input
Control Parameters (ICP) used to generate the filtered data and statistics for
one example month, January of the 14th year for Case 388.
